Hi, I am new here and recently bought a Aquarius Aq15005 Aquarius 5 Rounded 5-Gallon Aquarium
from Amazon and the current from the Power Filter that came with it is too strong for my new Betta fish. He has to swim very hard when moving at the front of the tank to get from each side. I am going to do a sponge baffle and I just want to make sure that I do it right.
I ordered an Aquaclear Foam Insert and going to rubber-band a sponge on the outtake of the filter that came with the kit which is this:
Obviously the filter I have is a BioStream 5-15e model but this is the only picture of the filter I can find online and they look the same. The intake tube doesn't have a strong suction that disrupts my betta it is just the current from the flow of water coming out. In this other picture I found online it has a sponge on the inside so is it better for me to rubber-band the sponge on the outside or place it inside the filter behind the outtake?
The filter uses Tetra Whisper Bio-Bag Medium Size Cartridges if that will have any effect on the sponge baffle.
